Remedy
Do not change the speed during deceleration or
stoppage caused by a stop command or during
automatic deceleration under position control.
Change the new speed to a value within the range from
0 to the "speed limit value."
Correct the ON/OFF timing of the "M code OFF
request." (Refer to section 12.6.3)
Specify the end of operation at the 50th point. (Refer to
Chapter 10)
Reduce the FOR to NEXT nesting structure to one.
(Refer to section 10.3.9)
Do not turn ON the speed/position changeover signal
during acceleration.
(Refer to section 9.2.9)
Issue a speed change request at a position where the
sufficient remaining distance is left.
Do not specify "1: Step continue" in the "step waiting"
axis status.
Do not set "1: Step continue" or "2: Restart" in the axis
operation status of "step error occurring", "error
occurring", "waiting", "stopped", "servo has not been
connected" or "in servo OFF".
Change "external start function selection" in detail
parameter 2 to within the setting range.
Change the positioning data to an address or
movement amount sufficient for deceleration.
Change the command speed to within the setting
range.
